Loop Interactive does not collect, sell, or share personal data through MathLib. The app has no accounts, analytics, advertising, tracking, or cloud sync.
Saved formula names, inputs, expressions, and settings are stored locally on your device. Scratch calculations are temporary unless you explicitly save them as a formula. Calculations, the formula catalog, and the reference work offline using resources bundled with the app.
MathLib uses Apple's StoreKit services to offer the one-time MathLib Pro purchase, check purchase entitlements, and restore purchases. These services may communicate with Apple and require App Store access. Apple processes payments; Loop Interactive does not receive your payment-card details. Apple's handling of purchase and account information is described in Apple's Privacy Policy.
You can delete saved formulas in the app. Deleting the app removes its local app data, subject to your device's operating-system backup and deletion behavior.
If you contact support, you choose what information to share so we can respond. Do not include private formulas or other sensitive information in a support request. See MathLib Support for contact details.
This policy will be updated before any release that changes these practices.
